pplication fi1d September 8, 1921. Serial No, 499,172.

The invention relates to insulators, and more particularly to means for connectifig-insulators to supports or to other insulators,

The principal object of my invention,

broadly stated, is to provide a novel "form of metallic connecting devic suitable for use with insulators, said connecting device being easy andsirnplo to apply, possessing grea strength, and involving but few parts Jlnother object of my invention t0 "pro videai1inexpcnsive meansfor connecting hall strain insulators to guy ropes and tothe in sulating supporting toWers,tlie said connecting devices being so construCted and arranged as to permit the connection thereof by the line men without the use oftoolS otherthan those usually carried by such men.

Another .object of the invention is to pro vide a connecting device for insulatorsin which the parts of the. Connecter are so arranged thatthe breater the strain placed upon the cOupling wh ich joins the parts of the connector togethef the tighter this coupling be cornes.

To tliese and other ends the invention relates to various elements and combinationsof elements herein2tfter set torth, the novel features Whereof are pointed out in the claims.

In thedrawings, wherein have illustrated several enibodiments of the invention,-

Throughont the specification and drawings like parts are designated by like reference lai body of pQrcelain or other dielectric 1na- 'terial having projecting fro1n the'exterior sur' faces thereof a plurality of ribs 2 the object 01: xvhich is to increase the leakagdistance ovcr the surface of the insulator. Primarily these hall strain insulators are employed to insulate the guy repos by which' the t0Wer or pole carrying the niain conductor is supported, the ball strain insulator being inter posed at son1e convenient point in the Span between the anchjoror the guy rope and the cable or tower.

VVhile I have illustrated and described my connector in combination with a particulartype of insulator, it is to be understo0d that I do not lirnit noy invention to this type, since many other forins of insulator may be advantageously employed with the connector herci nafter set forth. Pierciiig the insulator at points spaced from the opposite ends and extending at right angles to each other are a plurality o f openings 3,3, the adjacent edges of the openings beirig preferably curved as at 4 to provide a curvd bearing Surface. To connect the ball strain insulator to the tower as is generally clone, and to the guy rope, I 1nay provide a twopart connecter 5 the portions 6and 7 ofwhich are preferablv 1nade of comparatively, heavy 3nd'stifl' galvanized wires 8L Th Wires 8 of each portion are bent or otherwise shaped into loop lorrn andtl1e end portions of eacli loop are then brought togetherand bent in wardly and rearWardly as shown at 9 and 10, respectively, to form hook s 11.. The closed or looped' end 12 of each portion is of such widtli as to receive the liooked portion 11 of tliecoactii1g part'of the conhector. Preferabl th portion 6 of the Connctor is adapted t0 en Q;agewith a suitable corinection in the guy rope or with the conductor support, as the case ruav be, and for this purpose it pro- VlClCCl With a be11d or apex 13 substantially midway of its length. The portion 7 is pref erably syrnmetrcally curved so as to l0sl fit the curved portions 4 of the opening a.

T0 assemble the device the hook 11 of the portion 6 is lirst interlocked with the loop 12 o1the portion 7 as shown in Fig. 3. The loop 12 ol the meml3er 6 is then entered through a suitable 1nember carried either by the tmvor or the guy rope, and then the 110011 11 of the portion 7 is cnter d and passed through the opening 3 in the insulatorz .llre loop 12 of the portion 6 thon torcod over the hook 11 of the portion 7 and the; parts are drawn into substantially the positi on .slrown in Fig. 2. From an inspecuori of this figure it Will loe observed that when the parts are in assemblod position the bill et earh l]00l 11 is in contact with the bo ly portion of the insulator, and it Wlll l) apparent to those skilled in the art that upon strain being placed upon the connecter the tendenoy of the parts is to crowd or force tire bills of the respective hooks into intimato contact with the adjacent wires of the respective portions. It Wlll thus be evident that the greater the strain placed upon the conneotor tne ti gl1ter W1ll the hooks close upon the coacting loops 12.

It might be here pointed out that the dameter of the openings in a hall strain insulator is limited and is generally three quartcrs of an inch in width, and with this diameter of opening in the insulator I proferably employ a Wire 8 having a diameterof one quarter of an inch. Nire of this section has a maximum strcngth far in excess of that required under ordinary circumstances, and oonsequently with this size 0] wire there is a large margin of safety. It Will loe obvious, of course, that when the opening 3 has a diameter of three quarters of an inch the looped portions 12 which are spaced apart sufficiently to receive the bills of the respective hooks 11 will have a maximum diameter of at least one inch. As a result it is impossible te force the loops 12 et either portion 6 or 7 through the opening in the insulator. This difliculty is obviated by torming the hooked portions with a maximum diameter of three quarters of an inch measured over the hook, thus permitting the hooks 11 to ireely enter the openings 3 in the insulator loody, This form of hook is rendered possible since the bills of the hooks need only l1e spaced from the main body a distance sufcient to receive a single width of the wire.

\Vhile the construction described above is of great importance and is one of the features of myinvention, I donot Wish to be limited to either the exact diameter of wire or of the noted diameter of the openings in the insu lator, since the size of the openings and the size of the wire may be varied through a wide ran without departing from the spirit of my invention.

Referring now to Figs. 5 to 8, inclusive, wherein I have shown but a single member 14: constituting the connector, itavill be observed that this member is also formed ol compara tively heavy and stift galvanized wire and may be applied to the insulator loy projecting the hooked end 15 thereof through the opening 3 and then continuing the tl1reading of the connector until the loop 16 is substantially in the position shown in Fig. (3. The hook 15 thon engaged with the loop 16 and the wire bent or shaped to form an apex 17, whereupon the connection is made. t Will, et course, be

nuc e 7stoocl that prior to the connection of the 1100]: and loop 15 and 16 respectively, the connector 1.4. Will be passed throngh the coacting part either on a guy rope or tower, as the case may be. In this form also, owing to the position et the bill of the hook 15 and its engagement with the body of the insulator it will .be obvious that the greater the strain placed upon the connecter the greater will be the gripping action of the h0ok upon the p 16.

In Fi g. 9 I have shown a substitute for the wire in the form of a galvanized cable 18. Preferably I form a hook 19 at the open end of the cable, the said hook being produced by bending the ends Of the cable inwardly and rearwardly upon itself and by suitably conneeting; to the adjacent ends a sleeve or rnetal covering 20. A convenient way of connecting the sleeve 20 to the cable is to solder the same in place, the solder being forced into the opening through which the strancls of the cable extend so as to intimately connoct the cable to the sleeve. The method of associating the connecter shown in this modification with the insulator is identical with that already described with reference to Figs. 5 to 8, in clusive, and need not be further commented on. In this instance, however, af'ter the parts are interloclzed I preferably solder or other wise suitably connect the adjacent portion of the main bocly of the connector or cable 18 to the portion 20 so as to obviate slipping of the hook 19 which might be caused by the flexibility of the cable.

It Will be noted that in each instance there is provided a wide bearing area due to the engagement of two strands of wire in the insulator, and it will also be obvious that whether the device is of the multiple form or of the single unit type, a self locking feature is utilized topreventaccidental disengage ment of the parts under strain.

I clai m 1. The combination with' an insulator element having an opening therein, of a metallic connector passing through said opening, said connecter havinga hook and eye engagement between parts thereof, the bill of said hook being interposed between the insulator and a portion of said connector to prevent the accidental disengagement thereof.

2. The combination with an insulator of the strain type having a plurality of passages therethrough, of a metallio connecter coinprising a pair of semi-fiexible members each farnished with a closed eye at one end and a h0ok at the opposite end, the bills of said hooks beng adapted .to engage the body ofthe nsu1ator to prevent the disemgagement thereof.

3. A demountab1e insulator cmbinafzion comprising an nsu1ator haVing transverse passages nearopposte endsand at angles to each other,, an attaching link comprisimg hinged legs one of which passes through one of said passages and is adapted to fasten to the other' legs after having been passed through said passage of the insulator, the

other of said passages being formed to pass through said link when the link is closed on the insulatot, said last named passage and said link beng adapted to have wi'res an d the hke fascened therechroughh 4. In combnation, an insulator havhg a passagetherethromgh and a link comprising two hngedly connected memberS, one of said members having an end portion adapted to be removably postioned in said passage and pr0ject therethrough for detachable and im- 1n0vab1e engagement with the end of the other member.

In testimony whereof I aflx my Signature,
